Description
technical fieldthe invention belongs to rotovator technical field, be specifically related to the anti-reversing safety device of a kind of rotovator.
background technologyin prior art, rotovator is with tractor to complete cultivated, to harrow operation furrowing and harrowing machine tool, because of its have hack ability strong, plough after the features such as earth's surface is smooth, be widely used; Further, rotovator also can shred the root stubble of the plant being embedded in below earth's surface, is convenient to sower operation, for later stage sowing provides good kind bed; This rotovator can plough six mu of ground for one day, with traditional ox plough within one day, can only to plough more than one mu compared with, efficiency improves greatly; But the event of hurting sb.'s feelings about rotovator in recent years constantly occurs, six groups, tailo village, Dong Rangkou town, Badong County, the Yichang villager Song of such as 2014.06.20 CCTV news channel report is when the time in busy farming season uses rotovator operation, by in the Rotary tillage blade at rotovator heave in body rear, cause leg multiple fracture, blood vessel, nerve and soft tissue injury are serious, although life has kept, face the danger of amputation; 2008.10.13 advance villager in Huaiyuan County's shuts out certain, and when using rotovator, also by rotovator heave in Rotary tillage blade, the health causing below belly, all by rotovator strand wound, badly woundedly finally to be died; 2013.03.25 Ge Xi village, Xi San town, Muller city Chen is also by rotovator strand wound, and that live with ward with it is government office town, the Jianshui County villager Chen and Luxi Lee villager that are admitted to hospital on the same day, and two per capita by rotovator strand wound, and rescue of being admitted to hospital on the same day; The above-mentioned rotovator enumerated event of hurting sb.'s feelings is real event entirely, but this and more occurred in reality, has rotovator lethal events of hurting sb.'s feelings to occur every year; Although inform the main points that the buyer should be noted that in concrete sales process, and equipment itself also indicates warning poster, cannot ensure that in concrete operating process operator operates according to regular operating procedure completely; During concrete operations, rotovator engage a gear starts, after starting, Rotary tillage blade rotates fast thereupon, when needing to shift rotovator when field transfer, excessively ditch, excessively stalk, all require extinguish engine or hang over neutral, lift transfer by two people, lift fortune if do not extinguish to save time or do not hang neutral, after rollover, very easily strand is hurted sb.'s feelings; Particularly when rotovator changes to reverse gear by forward gear, rotary blade sector-meeting is reversed thereupon simultaneously, if now operating personnel can not the rotovator that falls away of stable control, the inertia be easy to by rotovator falls away rapidly washes upside down, the Rotary tillage blade at rotovator rear will switch to the foot of people, once be switched to by blade, it is upper mobile that rotovator will ride over people very easily, people then cannot break away from, consequence is hardly imaginable, even if at the outer setting protective cover of rotovator cutter, the transfer motion power of equipment itself also cannot be stopped; And rotovator is hurted sb.'s feelings and is had close relationship with the structure of equipment itself and power transmission, the blade at rotovator rear is connected with driving engine by power transmission shaft, namely blade is the main cause that accident occurs along with one, engine carries out rotating, therefore, the improvement of equipment itself is just seemed particularly important.
summary of the inventionthe object of the invention is to solve prior art to there is Rotary tillage blade and easily to reverse the technical problem of hurting sb.'s feelings, provide a kind of rotovator anti-reversing safety device, to overcome the deficiencies in the prior art.
To achieve these goals, the anti-reversing safety device of a kind of rotovator of the present invention, it comprises connection bracket; The front end of described connection bracket is provided with the splined shaft be in transmission connection with engine mission, and rear end is provided with the cutter shaft of band blade; Described splined shaft and cutter shaft are fixedly connected on support respectively by bearing block; Its main points are that same one end of described splined shaft and cutter shaft is respectively equipped with driven gear and knife shaft gear; Described driven gear is that axle center is rotationally connected with splined shaft, and the internal diameter of described knife shaft gear and cutter shaft engage each other and be in transmission connection; Described driven gear is in transmission connection by travelling gear and knife shaft gear; Described splined shaft one end is provided with internal diameter engages each other transmission one way engagement runner with it; Described one way engagement runner is positioned at the outside of driven gear, and is engaged each other by the unidirectional tooth in inclined-plane with the opposite place, inner side of driven gear, and carries out single-direction transmission connection; The outside of described one way engagement runner is connected with the catch elasticity of spline axial end by a spring.
The opposite place, inner side of described driven gear and one way engagement runner is fixed with the unidirectional tooth in inclined-plane respectively; The unidirectional tooth in described inclined-plane is provided with inclined-plane and end face; The unidirectional tooth in inclined-plane inside described driven gear mutually oppositely misplaces with the unidirectional tooth in inclined-plane inside one way engagement runner and engages.
In order to airtight protection gear, the side of described connection bracket is provided with gear seal closure.
In order to protect operating personnel to a greater extent, above the cutter shaft of described connection bracket rear end, be provided with protective cover.
Structure of the present invention is simple, easy to use, because the opposite place, inner side of driven gear and one way engagement runner is respectively equipped with the unidirectional tooth in inclined-plane, and the engagement that mutually oppositely misplaces, when splined shaft carries out Power output to one way engagement runner, the end face of the unidirectional tooth of one way engagement runner ramp and the end face of the unidirectional tooth of driven gear ramp bonded to each other, thus carry out Power output, and movable arbor is with to rotate under the transmission of travelling gear; When being linked into reverse gear, the unidirectional tooth in inclined-plane on driven gear and one way engagement runner reversely rotates, one way engagement runner can be contacted to axle head displacement after inclined-plane is stressed, driven gear and one way engagement runner are departed from mutually, and reset under the action of the spring, thus driven gear does not rotate when realizing reversing, power then cannot export cutter shaft place to, and cutter shaft does not rotate.The invention solves prior art Rotary tillage blade easily to reverse the technical problem of hurting sb.'s feelings.
